The Sajo mill is here

(1/32) > >>

Trion:
The mill arrived yesterday night, so I thought I'd start a thread about it here. Will be writing the thread similarly to the lathes thread, as a project of the machine and how I try to improve it. I am a newb to milling, so I'll be asking a lot of questions. In return, I'll take a lot of pictures hoping to entertain and possibly inspire some of you :dremel:

Short facts on the machine:
Sajo UF 52 Dual Mill
Year of make: 1971
Table size 1250x300mm (49,2"x11,8")
Feed on all axes, movement X/Y/Z 850/210/465mm.
Vertical and horizontal spindle are driven by separate engines 5 and 5,5hp respectively.
ISO 40 Spindles

Yeah, I know, I know  :worthless: ......


The machine came by truck, and a friend of mine was so kind to lend me his tractor. It's still snowy outside, and the road was bumpy so I drove it to it's home at a carefull 0,9km/h :coffee:


Everything went well, and the machine found it's place in the workshop




Machine tag



Some details of the machine:
The table had a few marks on it




If I have understood it right, then this is a small oil pump to lubricate the table and ways! It is ment for extra lubrication, while there is said to be some sort of permanent lubrication system that is activated by table movement. Not sure on this though..


Buttons to run the machine


Oil level for the table


The feed has built in end stop's on all axes :thumbup:


Lever for X-feed


And this is where the end stops put the lever out of feed mode. To my surprise, the table has a degree scale, which could mean that it is possible to swing the table :beer:


Front of the table. The lever to the right with the arrow behind has yet to reveal it's function, just like that flat screw sticking out of the dust cover..


Beneath the table


Locking of Y-axis, and end stops for feed. I assume the square headed bolts are the ones that have to be loosened to allow me to swing the table


A bit more concerning was the Z-axis. The end stop brackets are missing, and even worse, the Z-axis movement lock was also engaged - god knows how long it has been like that. It sure didn't make any difference to the force required to turn the Z-axis handle...


Here is how the top of the ways look. There are some random edge marks which I'm unsure of how were made


The strange surface pattern on the least used parts of the machine


But further down these are worn off, and the ways seem wavy when running a finger across



Here are the handles for changing the speeds for the horizontal spindle


Handles for changing speeds for the vertical spindle. These are very easy to use, and require little force. Think I'm going to get to like those!


I really like the oil plugs which are found around the entire machine :)


The vertical spindle has its motor mounted inside the boom, that allows for free movement of the boom, positioning the spindle in any desired position along the Y-axis. For acced convenience, the Sajo engineers added a "tooth rack" and a handle to simplyfy movement :thumbup:


Vertical head, with 50mm quill, fine feed handwheel, lock and end stop




The handles for both quill movements are missing. I sense a job for the lathe coming up ::)


Maximum quill extension


ISO 40 taper, missing a "tooth"


The othe vertical head the machine came with..









The one horizontal bearing block the machine came with. Is it normal for those to have oil inside?



Luckily the machine was made before one started to have walk-in electrical cabinets :lol:


Ampere-meters for horizontal and vertical spindle


They did however manage to squeeze in qute a few fuses into that small box..


Additional buttons controlling coolant on/of, spindle direction, use of spindle, horizontal, vertical or both, unknown and machine power


The contents of the cabinet..


Initially I didn't know the age of the machine, but I found some electrical documentation with this date on:


Here are the schematics if anyone should need them












They even thougt of adding an extra outlet for a light! :clap:



Now on for some actual "work". Lacking ISO 40 tooling, a vise and an electrical connector i started to clean of the machine.




Quite satisfied with how it looks, considering it beeing 39 years old.







Now on for a few questions:
- How can I measure the possible effect of the wear on the Z axis ways?
- I'm thinking of a Kurt D675 vise, suggestions for better alternatives? Will I get use of a vice with swivel?
- I have no 40 taper tooling, but having read that the only difference lies the drawbar, I'm thinking of buying something american from ebay, as they are half the price of SK 40. It would be nice to be able to use the same drawbar on all holders, what should I get, BT 40 or CAT 40?
- When buying tool holders, should I get a holder for ER collets, or endmill holders for each endmill?
- What's most common/convenient of ER32 or ER 40?

That's quite a beast you have there .... looks good though ...  :clap:

Someone is going to have a lot of fun with that  :dremel:

Looks like you have a great machine there. A bit of work to clean it up and repair or replace a few items and you will have it running like a fine tuned machine. I will be watching your progress and wish you good luck with it.  :ddb: :ddb:

Thanks for all the pictures, they were great.  :D

Cheers  :beer:

That machine looks a real beast  :bugeye: You will have fun with that :thumbup:

chuck foster:
now that's a serious mill  :bugeye:

i can't wait to see what you build with that  :thumbup:  :dremel:

chuck (now suffering from machine/tool envy)  :wave:
